43 p, 808.2 KB ABC of SV : limited information likelihood inference in stochastic volatility jump-diffusion models / Creel, Michael (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Kristensen, Dennis (University College London)
We develop novel methods for estimation and filtering of continuous-time models with stochastic volatility and jumps using so-called Approximate Bayesian Computation which build likelihoods based on limited information. [...]

26 p, 509.9 KB Neural nets for indirect inference / Creel, Michael (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica)
For simulable models, neural networks are used to approximate the limited information posterior mean, which conditions on a vector of statistics, rather than on the full sample. Because the model is simulable, training and testing samples may be generated with sizes large enough to train well a net that is large enough, in terms of number of hidden layers and neurons, to learn the limited information posterior mean with good accuracy. [...]

15 p, 137.4 KB Indirect inference for survival data / Turnbull, Bruce W. (Cornell University) ; Jiang, Wenxin (Cornell University)
In this paper we describe the so-called "indirect" method of inference, originally developed from the econometric literature, and apply it to survival analyses of two data sets with repeated events. This method is often more convenient computationally than maximum likelihood estimation when handling such model complexities as random effects and measurement error, for example; and it can also serve as a basis for robust inference with less stringent assumptions on the data generating mechanism.

This paper shows how neural networks may be used to approximate the limited information posterior mean of a simulable model. Because the model is simulable, training and testing samples may be generated with sizes large enough to train well a net that is large enough, in terms of number of hidden layers and neurons, to learn the limited information posterior mean with good accuracy.

32 p, 466.6 KB Indirect likelihood inference (revised) / Creel, Michael (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica) ; Kristensen, Dennis ; Universitat Autònoma de Barcelona. Unitat de Fonaments de l'Anàlisi Econòmica ; Institut d'Anàlisi Econòmica
Standard indirect Inference (II) estimators take a given finite-dimensional statistic, Z_{n} , and then estimate the parameters by matching the sample statistic with the model-implied population moment. [...]
